PEComa (clear cell "sugar" tumor) of the lung is a rare benign tumor of the lung probably arising from the perivascular epithelioid cells (PECs). We report a case of pulmonary PEComa arising from the periphery of the right lobe of a 64-year-old male. To our knowledge, this is the second case in the English literature diagnosed by fine needle aspiration biopsy. In this case report, the clinical, cytologic and immunohistochemical features clear cell "sugar" tumor of the lung are discussed and compared with the previously published literature. The differential diagnosis and methods for distinguishing the various clear cells lesions in the lung are discussed.
肺PEComa（透明细胞“糖”瘤）是一种罕见的肺良性肿瘤，可能起源于血管周上皮样细胞（PEC）。我们报告一例64岁男性右肺叶周边发生的肺PEComa病例。据我们所知，这是英文文献中第二例经细针穿刺活检确诊的病例。在本病例报告中，讨论了肺透明细胞“糖”瘤的临床、细胞学和免疫组化特征，并与先前发表的文献进行了比较。还讨论了肺内各种透明细胞病变的鉴别诊断及方法。
